2 The Plastics Experts. MINELINE is currently the most advanced stage of development in the evolution of piping systems for the mining industries. Whereas other pipe materials suffer from severe erosion and corrosion, AGRU MINELINE scores with far better durability than other options. The AGRU success story has been unfolding now for around seven decades. Founded back in 1948 by Alois Gruber senior, nowadays the company is one of the world s most important single-source suppliers for piping systems, semi-finished products, concrete protection liners and lining systems made from engineering plastics. Our ability to supply everything from a single source sets us apart. We use only top-grade thermoplastic polymers as our raw materials. When it comes to application-technical consulting, we are your best partner in the field. Quality At AGRU, customer satisfaction comes first. Technical consultations, training courses, welding instruction and expert supervision on site are essential parts. The AGRU quality assurance system is compliant with ISO 9001:2008 and its environmental management system fulfils ISO 14001:2004. This in turn ensures that the products comply with international norms, as monitored and evaluated on an ongoing basis by independent testing agencies standards. The start-to-finish attention to quality ensures that the products meet and beat the strictest technical specifications, providing safe operation within gas, water and wastewater infrastructures.

3 MINELINE Reduced maintenance and longer lifespan MINELINE is an entire piping system designed and tested especially for the transport of abrasive media. The innovative multi-layer design guarantees robustness and dependability for a longer lifespan and high cost-efficiency. Economic mining operations Longer service life because of the abrasion-resistant layer The inner layer offers high abrasion resistance and prevents media adhesion better durability than conventional metal and PE pipes maintenance intervals are significantly longer much higher productivity because of shorter downtimes Minimal thermal expansion White outer layer reflects sunlight A white surface significantly reduces the pipe wall temperature reduced abrasion due to less snaking of the pipeline higher pressure rating and reliability of the installed system due to lower pipe wall temperature Higher operational safety Greater wall thickness due to multi-layer design Multi-layer structure allows higher static loads for underground systems higher wall thickness (PE pipe + abrasion-resistant layer), so the pipes are more robust extra safety margin against water hammers, pressure surges and seismic activity offers all the advantages of PE pipes, such as high flexibility and resistance to crack propagation Protection inside the entire piping system All fittings have the abrasion-resistant layer Complete product range with protective layer, so no weak points in the installed system MINELINE is abrasion-resistant end to end, including all branches, bends and stub flanges the combination of butt welding and electrofusion welding ensures a perfect welded joint every time 3

4 MINELINE system The most cost-efficient solution The abrasion-resistant layer prolongs usable lifespan Better durability than conventional metal or PE pipes Maintenance intervals are significantly longer Higher productivity because of shorter downtimes Metal HDPE MINELINE II Triple dependability because of multi-layer design The abrasion-resistant inner layer prolongs usability enormously and prevents media adhesion The black core is made of PE 100-RC, offering all PE piping advantages such as flexibility, resistance to cracks, water hammers and seismic events The white outer layer is made of PE 100-RC and it reflects the sunbeams, reducing heat build-up and helping to minimize thermal expansion in the piping system The Plastics Experts. 4

5 End-to-end protection throughout the entire piping system A pipeline is only as good as its weakest link. AGRU MINELINE II fittings consist of three-layers, just like the pipe itself. White protective layer (PE 100-RC) Abrasionresistant layer Black core material (PE 100-RC) Combination welding, total dependability Combined butt and electrofusion welding in a single step means that there are no weak points in AGRU MINELINE II pipelines. So in conjunction with the outstanding material properties, this makes AGRU MINELINE the most cost-efficient solution. Butt welding Electrofusion welding Combined welding 5

6 MINELINE application For underground installation of MINELINE II pipelines, the white outer layer can be omitted. Application areas are the mining industry and the transport of highly abrasive media. In these fields, the MINELINE piping system will become indispensable due to its excellent abrasion resistance. Areas of application Mining and extraction industries - Transport of crushed ore - Transport of waste products Quarry industries - Transport of sand and natural stone - Transport of crushed stone Cement industry - Transport of lime, stones and slurries Chemicals industry - Transport of waste products, salts Dredging The Plastics Experts. 6

7 TESTS PROVE OUTSTANDING ABRASION RESISTANCE Coriolis sliding wear test Test conditions: Water with 26 % sand and solids, particle size 0.57 mm, test temperature 20 C Linear wear rate The Coriolis effect forces slurry from a rotating bowl through pipes in which material samples are fixed. MINELINE wins this sliding wear test clearly. linear wear rate [µm/h] MINELINE AR layer Cast basalt PE 100 PE 100-RC Steel PP-R PP-H Taber abrasion test (ASTM D 4060) Test conditions: Moving wheels weighing 1000 g and an abrasive coating, test temperature 20 C. The wheels rotate against the surface of the test specimen; their weight and the abrasive surface coating cause material erosion. Weight loss after a certain number of cycles is measured. Also with this test procedure the MINELINE system shows clear advantages to the other test materials. loss of weight [g/1000 cykles] 1 0,9 0,8 0,7 0,6 0,5 0,4 0,3 0,2 0,1 Loss of weight 0 MINELINE AR layer PE-HMW PE-X PP HDPE POM PVC Accelerated wear test Test conditions: Water with 15 % sand, particle size mm, test duration: 74.5 h, slurry changed every 6 h.

8 MINELINE product range The MINELINE supply range differentiates between 2 pipe types, which have been optimized for aboveground installation. MINELINE I pipes have a white protective layer outside but have no extra abrasion resistant layer inside. They have the good abrasion resistance of HDPE. The white outer protective layer reflects the sunlight, preventing this way the heating of the pipe of up to 70 C. For this reason, the strength and pressure resistance of the pipe remain even under intensive solar radiation. MINELINE II features the same white outside protective layer and also has an extreme abrasion resistant inner layer. Depending on the transported media, MINELINE II pipes offer a further improved life span than MINELINE I pipes. MINELINE fittings are built up the same way as MINELINE II pipes with the additional, abrasive resistant layer. This is important because especially in bends and tees, the abrasion is much higher than in straight pipes. The Plastics Experts. 8

Because of the high installation depth, heavy wall SDR 7,4 MINELINE II pipes were applied. Easy handling AGRU MINELINE is a lightweight compared to metal pipes and it scores extra points for long service life and easy installation. 11
